Castle: Sometimes when I’m trying to figure out how a character of mine does something I will walk the crime scene. This one time I was trying to figure out how to throw someone off the empire state building and that movie Sleepless in Seattle had just come out, so many lonely women approached me thinking I was their Tom Hanks, I got laid...Beckett: Castle!

Beckett: That's the difference between a novel and the real world, Castle. A cop doesn't get to decide how the story ends.

Beckett: I guess your Nikki Heat has a back story now, Castle.
Castle: I don't know. I did kinda liked the hooker by day, cop by night thing. But, I guess a heavy emotional angle could work too.
Beckett: Well, don't bewilder your audience with substance on my account, Castle.

Castle: People don't disappear off the face of the earth.
Ryan: Sure they do. Quantum physics, alien abductions, Schrödinger's cat. One minute you're getting a hot dog in the park, the next you're fighting off Sleestaks on the far side of a dimensional rift.

Beckett: She's melting.
Castle: Maybe we should be looking for ruby slippers.
Beckett: Yeah, while you're at it, why don't you should look for some flying monkeys, maybe they left her here.

Beckett: (about the victim) She's melting. Castle: Maybe we should be looking for ruby slippers. Beckett: Yeah, while you're at it, why don't you look for flying monkeys. Maybe they left her here. This is a reference to the 1939 film The Wizard of Oz adapted from the book by the same name written by L. Frank Baum. The screenplay was written by Noel Langley, Florence Ryerson and Edgar Allen Woolf and the film was directed by Victor Fleming.

Ryan: Sure they do. Quantum physics, alien abductions, Schrödinger's cat. One minute you're getting a hot dog in the park, the next you're fighting off Sleestaks on the far side of a dimensional rift.
Schrödinger's cat is a paradox devised by Austrian physicist Erwin Schrödinger in 1935. Schrödinger theorized that a cat in a box with a can of poison gas activated by the decay of a radioactive atom would, at any one instant, be both dead and alive at the same time. The superposition of two states collapses to one state or the other only when the box is opened and the cat observed. Schrodinger created the thought experiment to show the conflict between quantum level behavior and macroscopic behavior.
Sleestaks are large, scary, green humanoids with both reptilian and insectoid features from the 70's TV series Land of the Lost.

Det. Becket: How'd you know?
Castle: Spidey-sense.
"Spidey-sense" (more commonly called "spider-sense") is a precognitive power possessed by the Marvel Comics superhero Spider-Man.
